Hang two kings holding the throne after revolution (5)
I believe the answer is:
knack
'hang' is the definition.
(I know that hang can be written as knack)
'two kings holding the throne after revolution' is the wordplay.
'two kings' means two replacements for 'king'.
'king' becomes 'K' (abbreviation for king in chess).
'king' becomes 'K' (abbreviation for king in chess).
'holding' indicates putting letters inside.
'the throne' becomes 'can' (synonyms).
'after revolution' says the letters should be written backwards (letters revolve back).
'k'+'k'='kk'
'kk' going around 'can' is 'kcank'.
'kcank' written backwards gives 'KNACK'.
(Other definitions for knack that I've seen before include "Gift" , "Ability, facility" , "Slope" , "Special ability" , "Skill in doing something" .)
